First, you need to separate the granulated compost fertilizer pellets from those that do not meet your requirements. For this, rotary drum screener can finish it perfectly. With sieving mesh rotation, it can divide pelletized compost fertilizer into the size of required, too large and too small. There are 1-20 t/h capacity models of compost screeners for you.

Next, you can grind the unqualified compost granules into fine powder for returning to the compost pellet making machine. For the returned compost pellets crushing the chain crusher is the best choice. Because of small space needed, you can put it closed to rotary screener directly. Namely, it don not need extra belt conveyor.

First, the most effective solution to recycle the spread powder in compost granulation is use professional dust collectors. Including cyclone dust collectors, water curtain dust collectors, and dust fall rooms. These devices capture airborne particles during compost pellet making, especially in the steps of compost drying and cooling. The compost material in the dust collecting system can be recycled to prepare granular compost fertilizer again.

In addition, for further reduce the waste in compost granulation, you can also add dust covers on machine where compost powder is easier to spread. Such as belt convey and screening. Here, YUSHUNXIN can offer you these customized machine to granulate compost in no waste.
